I've visited China a half dozen times.The first visit was in 1980...the most recent was last year.Even on the clearest day I experienced there the air was almost unbreatheable.The world's prevailing winds,IIRC,do travel from west to east (thus allowing Japan's balloon bombs to reach the western US and western Canada)so it seems possible that some of California's smog is from China.And maybe from Japan and (South) Korea as well.

But mainly from China.

the photos of the chonese smog...that Ive seen...in the last ten years...appear to have been taken in the midst...of a massive firestorm

Korea, Japan and most of China lay beneath the latitudes of the prevailing westerlies, bringing air from west to east. As these winds often achieve great altitude as in the jet streams, It is certain that substantial pollution from Asia reaches the North American continent.
